9 - 2 1/4 + 34=
6 1/2 + 2,75=
7,8 - 5 5/6=
7/8 : 5,6=
3/7 x 4,2=
2,8 : 7/12=
1 1/6 : 2,4=
3 1/9 : 1,4=

Answer 1

A) 3,2 - 1 3/5 = 3 2/10 - 1 3/5 = 32/10 - 8/5 = 160/10 - 16/10 = 184/16 = 72/5 =
14 4/5 
b) 45 + 3 2/3 = 4 5/10 + 3 2/3 = 45/10 + 11/3 = 56/10 
c) 2 3/5 - 1,4 = 2 3/5 - 1 4/10 = 6/10 - 4/10 = 2/10 
d) 9 - 2 1/4 + 34 = NWM
e) 6 1/2 + 2,75 = 13/2 + 2 75/100 = 88/100
f) 7,8 - 5 5/6 = 7 8/10 - 5 5/6 = 78/10 - 35/10 = 43/10 
g) 7/8 : 5,6 = 7/8 * 6/5 = 36/40 
h) 3,7 * 4,2 = 15,54 
i) 2,8 : 7/12 = 2 8/10 : 7 12/10 = 28/10 : 82/10 = 28/10 * 10/82 = 280/820
j) 1 1/6 : 2,4 = 1 1/6 : 2 4/10 = 7/6 : 24/10 = 7/6 * 10/24 = 240/134
